ABSTRACT

Objectives@#This study was conducted to evaluate the relationship among childhood maltreatment, cognitive function and emotion dysregulation in healthy adults who have not been diagnosed with existing mental diseases and do not report clinically significant levels of symptoms. @*Methods@#The participants were 66 healthy young adults aged 20 to 40 recruited from October 2021 to March 2022.Cognitive function, maltreatment experience, emotion dysregulation and depressive symptoms were evaluated. Their association was analyzed using Kendell’s tau coefficient. In addition, multiple linear regression was conducted to explain emotion dysregulation using cognitive measures. @*Results@#As a results of Kendall’s tau coefficient calculation, emotional abuse experience showed a significant negative correlation with cognitive functions such as perceptual reasoning, working memory and processing speed. The degree of difficulty in emotion regulation reported a significant positive correlation with processing speed among cognitive functions. In the multiple linear regression analysis, processing speed among the cognitive function measures might be revealed to be a factor that can affect emotion regulation even after excluding the influence of other measures. @*Conclusions@#The results of this preliminary study suggest that certain maltreatment experiences, such as emotional abuse, can affect cognitive decline, even if there is no clear mental illness, and the cognitive function can be associated with difficulties in emotional control.

ABSTRACT

Background@#Loss of companion animals can result in various psychological reactions, including complicated grief, depression, anxiety, and insomnia. However, research on the prevalence of patients requiring clinical intervention is limited. Moreover, research examining the relationship between childhood trauma and psychological symptoms after pet loss is lacking. Therefore, this study aimed to investigate the rates of clinically significant psychological distress after pet loss and the impact of childhood trauma on adults who have experienced pet loss. @*Methods@#An online survey was conducted with non-clinical adult participants who had experienced the loss of a companion animal. Psychiatric characteristics were evaluated using standardized assessments, including the Inventory of Complicated Grief (ICG), the Patient Health Questionnaire-9 (PHQ-9), the Generalized Anxiety Disorder-7 (GAD-7), and the Insomnia Severity Index (ISI). Childhood trauma was evaluated using the Childhood Trauma Questionnaire (CTQ). @*Results@#In a sample of 137 individuals who had experienced pet loss, the percentages of those who exceeded the cutoff points were 55% for the ICG, 52% for the PHQ-9, 40% for the GAD-7, and 32% for the ISI. The group that reported childhood trauma exhibited significantly higher scores on the ICG (t = 2.16, P = 0.032), PHQ-9 (t = 3.05, P = 0.003), GAD-7 (t = 2.61, P = 0.010), and ISI (t = 2.11, P = 0.037) than in the group without childhood trauma.For participants who experienced pet loss for less than one year, there was no significant difference in the ICG between the trauma and non-trauma groups, as both had extremely high scores. However, the trauma group had a significantly higher PHQ-9 (t = 2.58,P = 0.012) than the non-trauma group. In contrast, for participants who experienced pet loss for more than one year, the trauma group had a significantly higher ICG (t = 2.22, P = 0.03) than the non-trauma group, while there was no significant difference in the PHQ-9. Additionally, the emotional abuse scores on the CTQ were most significantly correlated with the ICG scores even after controlling for depressive symptoms. @*Conclusion@#People who experienced pet loss had significant psychological symptoms, ranging from 32% to 55%. Childhood trauma experiences affect complicated grief, depressive symptoms, anxiety symptoms, insomnia and prolonged grief disorder after pet loss. After pet loss, people with childhood trauma may require more psychological help than those without trauma.

ABSTRACT

Methods@#Three groups were included in this study: remitted schizophrenia patients (n=56), patients in euthymic states of bipolar I disorder (n=52), and healthy control (n=57), who were matched on sex, age, years of education. The Continuous Performance Test of the AX version (AXCPT) was used to evaluate the cognitive control function. Intelligence, psychopathology, and psychomotor speed were also examined. The degree of cognitive control deficits was assessed by the commission error rates, correct response times, and the d’ values. @*Results@#Both patient groups performed worse in the AX and BX trials than the healthy control. Both patient groups showed a delayed response in all trials than the healthy control. The d’ value was the highest in the healthy control group, but there were no significant differences between the two patient groups. The profile of defects in the two patient groups was the same, with the BX trial having the highest defects in the order of the AX, BY, and AY trials. @*Conclusion@#These findings indicate that cognitive control is impaired in patients with schizophrenia and bipolar I disorder. Impairments in cognitive control are likely to be a possible shared pathophysiological marker for both disorders.
